oouison and Ernest Degenhart, Fors to The Capehart Cor-` Application September 12?',v 1930, Serial No. 481,386 19 Claims. (Cl. 274-10) This invention relates to an automatic phonograph andparticularly to that type of phonograph which is adapted to play a series of the disk type of record in a desired sequence. This phonog'raph is adapted to useI both of the common standard sizes of diskvrecords either in a mixed assortment or in groupsof a singlefsize. The parts are so arranged that the records are played in the order in which they are placed in the machine and both sides of each record are played before a second record is used. By this means, a long composition, such asv a symphony or an opera, may be played in its proper sequence when succeeding portions thereof are recorded on opposite sides of the same record.

The principal features of the invention reside in a novel form of mechanism by means of Which the various functions of the machine are performed.-

One feature of the invention resides in the no vel method and mechanism used for centering the various sized records upon the playing turntable.

Another feature residesv in the mechanism used for locating the tone arm and stylus for beginning the playing of the records of various sizes.

Another important feature resides in the form of mechanism used for reversing the record for` playing the opposite side and for returning the record to a storage magazine.

Otherobjects and features andthe full nature of the invention will be understood from the accompanying drawings andthe following description and claims:

Framework; and power mechanism The stationary frame of. the machine includes a pair of lside plates 20 and 21 connected at their lower edges by a horizontal bed plate 22 to which are fastened supporting feet 23. An inclined plate 24 is fastened between the plates 20 and 21. A yoke 25 is also fastened to said plates and extends across the rear of the machine.

An electric motor 26 is mounted uponthe bed plate 22 and carries a pulley 2'1 about which is trained a belt 28. The belt 28 also passes ,about a pulley 29 carried upon a horizontal shaft 30 supported upon suitable bearings attached to the plate 21. The shaft 30 also carries a worm 31 meshing with a worm wheel 32 carried upon a 'horizontal shaft 33 supported in suitable bearings upon the plate 24. The shaft 33 also carries a pinion 34 meshing with a gear 35 carried upon .acam shaft 36. The shaft 36l is supported in bearings carried by the plates 20 and 21 and carries cams 3'7, 38 and 39. The said cams are used to'control the various movements" of the mechanism as hereinafter set forth. The shaft 33 carries a sprocket 40 about which is trained a sprocket chain 41. The chain 41 also passes about sprockets l42, 43 and 44. The sprocket 42.

runs freely' upon a shaft 45 extending between the plates 20 and 21. The sprocket v43 runs freely on a similar shaft 46. The sprocket 44 is lcarried upon a stub shaft 47, in turn, supported upon a bearing bracket 48 formed upon the plate 24. The sizes of the various gears and sprockets so far described and 'the' number of links in the chain 41 are so chosen that the calm shaft 36 and the chain 41zeach 'makes one complete revolution during one cycle lof operations including the playing of both sidesI of a single record. a -r Storage magazine and mechanism for removing records therefrom The plate 24 carries a pair of ribs 49 and a pair of oppositely positioned record guideways 50 having upwardly extending outer edges 51. Ahorizontally extending rod 5-2l is fastened to each of the plates 20 and 21. Each of the said rods carries a cylindrical member 53 positioned as best shown in Figs. 1 and 4. The outer surfaces of the record guides.50 and ofthe ribs 49 are located in substantially the same plane and may, therefore, serve as a rest fora pile of'records 54 'asshown in Figs. 1 and 3. When placed in position upon the ribs49 and guides 50, the lower edges of the tion to maintain the lowermost recordv in position beneath the stack.

As shown in Fig. 1', the portion of the chain 41 passing between sprocketsl44 and 40, passesf above the plate 24 and between the ribs 49. The

- Said attachmentsfrom ybeneath the stack and is projected downwardly along the surface of the ribs 49 and guideways 50. When the said record has cleared the bottom of the stack, it is free to slide by gravity and comes to 'rest upon a pair of outwardly and upwardly extending stop members 56 carried upon the plate 24.` `(See Fig. 11.) It is to be noted that the records in the magazine may be of any size or of mixed sizes. Since the records are supported in their nal position by the stop members 56 at .two points only, the centering hole of the record will always be found upon the median plane between these .two points. .It

\' j is also to be noted that the fact that two attachments 55 are used upon thech'ain 41 to remove the records from the magazine insures that the said records will be propelled from the magazine in substantially a straight line. There is, therefore, no necessity for placing special -guideways for the various sizes of records.

Turntable manipulating mechanism P A horizontal shaft 5 7 is supported upon suitable bearings on the plates 20 and 21. lAdjacent the cam 37, the said shaft 57 carries an ,arm 58, in

. turn, carrying a roller 59. engaging the irregular periphery of the said cam. By lthis means the shaft 57 is rocked as desired. The shaft 57 also carries a pair of arms 60 `which are downwardly curved to pass beneath the shaft 33 and which thereafter extend in asubstantially horizontal direction to support a shelf 61 upon which is carried a playing turntable 62. Beneath' the shelf 61 there is fastened a turntable driving unit 63 including a motor 64, a governor 65 and suitable gearing for rotating the turntable at the desired speed.

The cam 37 is formed with a deeply indented V portion 66. This portion of the cam reaches roller 59 in the rotation of shaft 36 at a timejust before the engagement of the lowermost record in the magazine by the attachments 55. When this takes place, the shaft 57 is free to rock, permitting the arms 60 and the turntable and motorncarried thereby to drop into the position shownlin Fig. 11. Thereafter the record 54 is moved from the magazine and broughtA to rest upon the stop'mem-4 bers 56 as previously described.

During this movement of the record, the cam 37 has rotated to bring an outwardly extending. shoulder portion r67 thereof into 'engagement with the l roller 59. The shaft 57 is thereby returned to its -thefrecord 'I'his vis trueno matter which size of initial position carrying with it the arms 60,' turntable 62 and the record 54. In Fig. '11, 'it will be noticed that the centering pin 68 of the turntable is in a position considerably below the center of 54 will be outwardly moved upon the stop members-)56. vIn this movement, the centering hole of 75 plane between the stop members 56. -The center-A the record isf'always maintained onthe median eventually engages the centering A pair of counterbalance Weights 69 Aare carried I by the shaft 57 by means of arms 70. These weights are so positioned and adjusted as to approximately counterbalance the weight..of thel turntable and motorin their movement about the shaft A57.

Tone arm manipulating mechanism AA tone arm 71 is pivotally mounted by means of a pin 72 upon a lug 73. The lug 73 is formed as part of a cylindrical sleeve 74 supported Within a lshell 75 iixedly carried upon a' platform 76. The platform 76 is supported upon a bracket 77 carried upon the plate member 21; The tone arm` 71 supports at its outer end a sound box 78, in turn, carrying the usual form of stylus 79. l By this form of support, the tone armis free to oscillate about the vertical axis of the shell 75 in following the record groove of the record. It is also free for movement about the horizontal axis of the pin 72. l,

The chain 41 carries a pair of pins 80, each of which is adapted to engagea pin 81 at the completion of playing of onev side of each record. The pin 8l is carried upon a yoke 82, in turn, forming a part of a sleeve 83 surrounding the yshaft 45. The sleeve 83 is freefto rock upon the said shaft and carries -an upwardlyA extending arm 84, to which is fastened a clevis 85 attached to a horizontally extending rod 86. The rod 86 has a portion 87 turned at rightI angles to the main part thereof and to 'which is fastened a plate 88 ported beneath the plate 76.

An arm 90 is mounted for pivotal movement about a vertical axis upon the plate 76. A shorter varm 91 is xedly connected to the arm 90 and is free to move therewith. The arm 91 carries a spring pressed friction pad 92 engaging the slidably supported in a guide 89 which is sup- -the same time, the portion 87 of rod 864 engages a pin 94 carried upon aC bracketvme'mber 95 fastened to the lower portion of the sleeve 74. By this means, the tone arm yalso i`s moved to the right in Fig. 1 to a position clear of the record. In .this position, a plate '96 upon the side of the `upper surface of the plate 88. By this meanssound box 78 engages a notch v97 in a plate 98 carried by the arm 90, as shown in Fig.- 8.` As previously stated, this movement -of the parts takes place immediately after the playing of each side of each record. The tone arm and arm 90 are moved thereby to a position clear ofthe record and maintainthat position ,during the movement of the turntable tobring the new recorduinto playing position. .A

When the turntable has been elevated to bring a position slightly below the normal playing po-v sition. With the parts in that position, a pin 'up a new record, the roller 59 is travelling upon i 100 carried upon the downwardly travelling flight of chain 41 engages an arm 101 carried upon the sleeve 83 and moves-the said arm downward. This movement rocks -the, sleeve 83 and retracts vportion 112 bent sion springs 114 and carried by ayoke 105 I 1,962,858 3 the rod 86, carrying with it the plate 88, friction Record reversing mechanism pad 92, arm 90 and the tone arm 7l. This movement proceeds until a gauge plate 102 carried upon the outer end of arm 90 engages the edge of the record upon the turntable; as shown in Fig. 8. In this position.. the plate 102 acts as a gauge to position the stylus 79 accurately above the position for the start of playing of the record. Upon the engagement of the plate 102 with the record, the friction pad 92 slips upon the plate 88. By this means, the stylus 79 is accurately positioned, no matter which size of record is carried by the turntable.

When' the parts halve reached the position shown in Fig. 8, the roller 59 rides upon an elevatedportion 103 table is caused thereby to move upward to the normal playing position as shown in Fig. 9. The record engages the stylus 79, lifting the plate 96 from its engagement withthe notch 97. Thereafter, the tone arm is free to follow the sound track upon the record. This movement of the turntable also frees the edge of the record from the gauge plate 102. Simultaneously, with this movement one of the pins 80 engages a pin 104 attachedto a double throw switch 106. The switch 106 by means of wiring connections, to be hereinafter described, stops the motor 26 and starts the turntable motor 64 for playing of a record. During the playing of the record. therefore, the rotation of the cam 37 is stopped and the roller A59 remains in position upon the elevated portion 103 of the said cam.

Tone arm electrical switch-A Upon the completion of playing of each record, the stylus reaches the braking groove of the record and causes the actuation ofV a mercuy 26 y mechanism now to bedescribed.

A plate 108 is carried upon the bracket "I7 and pivotally `supports by means of a pin 109, a lever 110. The mercury switch 107 is supported upon a carrier 111, also pivotally carried upon the plate 108. The carrier 111 has an upwardly extending at la right angle to engage a shoulder 113 upon the lever 110. A pair of ten- 115 serve normally to maintain the said engagement as shown in Fig. 10.

then pulls the carrier -ing to bring theportion 112 thereof in contact oscillating type of braking With the parts in this p position, the mercury switch 107 is in the open circuit position.

When the record in use has a spiral type of braking groove by means of which the. stylus is brought close to the center of the record, a pin 116 carried by/the bracket member 95 engages a cam 117 carried bythe lever,1 10 at the completion of playing of the record. When this takes place, the lever 110 is forced downwardly to break the engagement between the switch carrier por.- tion 112 and the shoulder 113. The spring 114 111 about its pivotal mountwith a stop 118 carried by the lever 110. In this position, the mercury switch 107 is in the closed circuit position and the motor 26.is started. l

When the record in useI is provided with the groove, the tone arm v is moved rapidly backward and forward at the completion of playing of a record. When this takes place, a spring pressed dog 119 carried by bracket 95 engages one of a plurality'of serrations 120 carried upon the lever 110. This engagement forces the lever 110 downwardly and operates the mercury switch 107 in the same manner as previously described.

of the cam 37. The turnr gagement Lwith the stylus 79, the tone arm 71 ,l

being then supported upon the upper end of a pin 122 carried by the sleevel 74. Thereupon, one of the pins 80 engages the pin 81 to move the tone arm from above. the record as previously described.

The cam 38, best shown in Fig. 2, has its operating face engaged by a. roller 123 carried upon a horizontal stern 124. The stem`124 is supported at one end in the. plate 20 and at the'opposite end is supported by a lever 126 normally maintains the roller 123 in contact with the operating surfacemof the cam 38. By

means of the said cam the stem 124 may, therefore, be longitudinally moved as required. A pin 127 carried by the stem 124 serves as a seat for a washer 128, in turn serving as a seat for a compression spring 129. The spring 129 abuts at its opposite erld against the lever 125 which, in turn, abuts against a pin 130 carried by the stem 124. By this means, when the stern is moved to the left in Fig. 2, the lever 125 /may be oseillated about its pivotal support 131. However, the force is applied tolever 125 through the compression 125. A tension spring spring `129 so that'when the lever meets with a predetermined resistance to movement, the said spring is compressed while the stem' 124 may continuel its movement.

At the upper end of the lever 125 there is connected a rod 132. The rod 132 extends through a centralhole in a squaredshaft 133. The shaft 133 is rotatably supported in a suitable bushing 134 carried by the plate 21. A similarsquared shaft 135 is similarly supported in a similar bushing 136 carried by plate 20. The squared shafts 133 and 135 are joined by means of a housing 137.

carries a rack 138 engaging a pinion 139 suitably supported within thehousing. The opposite side of the pinion 139 also engages a rack 140 attached.

The rod 132 extends Within the housing 137 and direction within the shaft 135. An arm 142 having a hub 143 is carried upon the squared shaft 133 and isslidable longitudinally of said shaft but is rotatable therewith. A similar arm 144 having a hub 145 is similarly carried upon squared shaft 135. A pin 146 extending through a slotted opening 147 in the shaft 133 engages the rod 132 and the hub, .143. Thus, the motion of rod 132 slides the hub 143 and arm 142 upon the shaft 133. Hub 145 is similarly fastened to the stem 141.by means of a pin 148 passing through a slotted opening 149 in the shaft 135. :At the outer end of the arm 142 there is carried a rotatable friction pad 150 adapted to engage the edge of the record upon the turntable. A similar' rotatable pad 151 is carried upon 144. The arms 142 and 144 normally rest upon supports 182 and 183 carried by plates 2l and 204 the outer end of arm in Fig. 6. Within the'said arm, a bushing 152 is carried by the squared shaft 13 5. A lever 153 having a hub'154 is rotatably mounted upon the said bushing and has a rearwardly extending portin 155 extending outside ofthe arm 44. lever 153` hasy pivotally attachedthereto a rod 156 terminating in a rack 157. The rack 1,57

engagespa pinion 158 freely mounted upon a pin 159 extending through the arm 144 and carrying the rotatable' pad 151. A tension spring 160 is fastened at one end to the rodI 156 and at the opposite end to the inner wall of the arm.144`

block 164 of rubber or other resilientmaterial is interposed between the surface of the arm 144 and the rotatable pad 151. By this means when the vrod 156 is moved to the left in Fig. 6, the pinion 158, pawl 162 andratchet 163 operate yto rotate the pad 151 against the friction applied thereto by the rubber block, 164. When the rod 156 is moved to the right, the friction of the block 164 maintains the pad-151 in a relatively stationary position while the pawl 162 freely A passes over the teeth ofthe ratchet wheel 163.

The cam 39 carried upon the shaft 36 engages a lever 165 pivotally mounted upon the plate 21 by means of apin 166. The lever 165 carries at its upper end a; plurality of gear teeth..167 engaging the teeth of a gear 168 carried upon the squared shaft-133. The lever 165 is normally maintained in engagement with the cam 39 by means of a tension spring 169 fastened at one end to the said lever and at the opposite end to the plate 21.v

Upon the completion of playing of the first side of a record the tone arm is moved from above the vrecord as previously described. The cam 38 then operates to move the pads 150 and 151 into engagement with the opposite edges of therecord upon the turntable. By means of the yielding connection of spring 129 the record is engaged irrespective of its size. Upon engagement of the record a. projecting portion 170 of cam 39 engages the lever 165 and by moving the same,'.

rotates the squared shafts 133 and 135 to elevate the'l arms 142 and 144 to the position shown by broken lines A in Fig. 6. During this motion the Yprojecting lever 155 engages a plate 171 carried 64 is started by the by an arm 172 attached to the shaft 57. By means of this engagement, thelever 153 is maintained in a relatively stationary position during the lifting lof the arms 142 and 144. The rack 157 is, therefore, moved as indicated in Fig. 6, a sufficient distance to rotate the record through 180 degrees.

As the projection 170 continues to rotate, it

.passes the lever v1 65 and permits 'the return of the arms 142 4and 144 to their lowered position,

thus placing the record upon the turntable with the opposite side uppermost. Cam 38 then operates to return the pads 150 and I151 to the position shown in Fig.` 4. The tone arm is then moved into playing position by the mechanism previously described. An elevated portion 173 of cam 37 then engages the roller`59 to bring the turntable into playing position and release the stylus for movement upon the record. The motor 26 is then stopped and the turntable motor mechanism previously described.

`Mechanism for returning-,record to magazine Upon the completion of playing ofthe second side of the record, the `mercury switch 107 is actuated to again start the motel. 26 as previreturn of arms Lacasse The ously described. The tone arm is againmoved fromabove the record. The cam 38 then operates to bring the pads 150 and 151 into engagement with the record. The roller 59 reaches the portion v66 of cam -37 and permits the turntable to be lowered into position to receive a new record. A projecting portion 174 of cam 39 then engages lever 165 to elevate the arms 142 and 144. The portion 174 projects further from the.l center of cam 39 than portion 170. The arms' 142 and 144 are, therefore, moved through a greater arc and are brought to the position shown by broken lines B in Fig. 6. i l

Since the shaft 57 has been moved to lower the turntable, the plate 171 has been removed from the path of the lever 155. The rubber block 164 is, therefore, able to maintain the pad 151 in a relatively stationary position with respect to arm 144. 'I'he record is, therefore, brought into position above the magazine with the side last to .be played facing downward. With the record rin this position, cam 38 operates-to move the pads 150 and 151 from ,their engagement with the record and the record is dropped upon the stack in the magazine. Cain 39 then operates .to permit the 100 142 and 144 to their horizontal position.

l 'Motor control.

In Fig. 12 is shown a diagram of electrical con- A nections for the control of the motors 26 and 64. The wires 175 and 176 are connected to anysuitable source ofcurrent supply. The wire is connected to gne terminal of each of the'motors 64 and 26. The Wire 176 is connected to one terminal of the mercury switch 107 and to the common terminal of the double throw switch 106.4 A wire 177 connects the .opposite terminal of the mercury switch 107 with one terminal of the switch 106 and also to the motor 2e.v The third terminsu ofy the double throw switch 106 is connected to the second terminal of the motor 64 by a wire 178. During f the playing of the record the mercuryswitch 107 is' normally in the open circuit position while the 1 switch 106 is in the position shown by dotted lines in Fig. 12. The motor 64 is, therefore, in operation whilethe motor 26 is stopped. I

Upon the' completion of playing of each side of each record, the mercury'switch 107 is moved to 1 ,the `closed circuit position to sLart the motor 26.
